The derail of the present invention is so constructed that it may beadapted for various sizes of rails and for various types of syst s,such, for instance, as those wherein the rat. is level or canted. It maybe constructed readily, as by fabrication, from a, number of componentparts which are or forged or from a number of parts which are cast intothe requisite shapes. It comprises but :a relatively few parts, may

3 be noted from the following description and from the drawings to whichreference is now had.

The derail, which is indicated as a whole by reference character it, isillustrated as being o the sliding but it should be understood atcertain features of the invention may utl zed in the construction ofother types of derails, for instance, as hinged derails.

The sliding derail illustrated in the includes two main portions. Theserail block E2 and a derail guide box, indicated as a whole by thereference character hi, upon which the block is slidably mounted. It isto the guide box that the present invention particularly pertains and itis, therefore, contern' ated that any desirable or suitable form ofderail block. may be used.

fhe illustated derail block 32 includes a su porting or body section it(see Fig. i) extending to one side from the derailing portion. it issupported on the guide box for what may be termed an up and overmovement, movable from a retracted position in illustrated in e to thewhich it is illulstrated in Figs. 1 u. ably supported in hearings to bee in greater detail hereinafter by a rearwardly extending generally hookshaped portion (see Fig. 2), a pair of intermediate laterall ex tendingbearing members 29 a d and a pair of forward main bearings 2 0113 one ofwhich illustrated in the drawings (see 3 and The derail block is alsoprovided with a plurality of downwardly extending lugs 2% near the rearso that suitable operating mechanism may attached to the derail block tomove it. Inasmuch as the operating mechanisms may take various forms,these have not been shown.

The derail g ide box includes a pair of vertical side plates 3b and 32,the former being at the left (Fig. 2) and being iden cal to the one atthe right except for the provision of a notch 3d at its upper surface,for a reason to be i ereinafter mentioned. The of the vertical sideplates may be noted best from 3, 4 and 5, particularly the latter. Themain portions thereof are generally rectangular but the ends adjacentthe rail extend generally down wardly and away from the rail. e er'eusions include a portion of inclination and portion 38 extending ne' 1vertically.

The derail block support...ig and guiding structures are secured to theinner sides of the side plates. These structures are identical, exceptfor one exception, s-- that only one Ll b reference characters.Referring now ticularly to Fig. 5, it be seen structures include agenerally holding-down shelf secured of the central portion of the surfconfiguration of ports and of end of the side plate.

The left holding-down shelf as indicated by reference characte region ofthe notch 3 8, for the rece ing means for the derail block. means may bea padlock (not shown).

The derail block is supported and guided ii part by the three pairs ofstructu elements just referred to. The holding down slves itcooperatewith bearings 2i; and 2 to revent undesired vertical movement of trieder:1

as it is slid between its two positions; the seats 52 are engaged by thebearing members 2% on the underside of the derail block whereby thederail block is moved vertically it moves from one position to another;and the pads i iserve to assist in preventing undesired lateral movementof the derail block. fhe two positions of the derail block areillustrated in Figs. 3 and 4:. In Fig. 3 the derail. block is shown inderailing posi tion on top of the rail. At this time the bearing membersare at the front sides of the seats d2 while bearings 22 are disposedsubstantially immediately below the forward ends of the holding-downshelves lil. In the retracted position illustrated in Fig. 4, thebearing members 2:; abut against the rear side of the seats and thebearing members 22 are below the rear of the holding-down shelves 49.The front end of the derail block is at this time supported by theapices of the seats 62.

The derail guide box comprises a standard shell adaptable to differentsizes of rails. It is designed to fit the highest rail of a series ofrails without change and may be adapted to fit lower rails by trimmingportions of the plates to and 32 and a front brace 56 shaped with areversed curve and abutting against the front edges of the side plates.Considered in another manner, the front ends of the side plates and thefront brace may be considered as being in clined generally downwardlyand away from the web of the rai1the construction constituting a sort ofa nose fitting underneath the rail head and adjacent the rail web. It ispreferred also that the width of the front cross brace be somewhatgreater than the distance between the side plates in order that it maybe secured, as by welding, to a pair of generally horizontally disposedtie flanges Eli and 52 which are adapted to be secured, as by welding,to the outer sides of the side plates. More will be said shortly abouttie flanges and the way in which they are secured to the side plates.

The derail as a whole is supported upon a pair of spaced apart ties Edby the tie flanges SE; and which are secured to the vertically disposedside plates. The tie flanges are preferably rectangular in shape and areprovided with apertures for the reception of spikes 58, by means ofwhich the structure is secured to the ties. The tie flanges have widthspreferably corresponding the projecting portions of the front crossbrace so that they may be secured to the brace.

The guide box shell includes also rear cross brace defining structure.This structure includes a curved top brace to, the downwardly projectingends of which abut against and are scoured to the top edges of thevertical side plates and 32, respectively. The structure includes alsovertically dispose-d cross brace 62 of gener' lly trapezoidal shape andsecured, as by welding, to the ends of the vertical side plates as andand the cross brace 86.

The vertical rear cross brace 62 is provided with a hearing so adaptedto cooperate with the derail blocl: bearing id. The bearing 64%, whichis illustrated in Fig. 2, is produced by cutting what may be termed asomewhat L-shaped slot SE in the lower portion of the vertical crossbrace.

A l'tlOlfll rigidity is supplied to the derail by middle side braces if;and 2 and rear side braces and it. Th middle side braces are generallytrian ular in shape and are secured to the outer and upper sides of thevertical side plates and horizontal tie flanges, respectively. The rearside braces constitute, in effect, extensions of the rear cross brace 62as they are configured to extend from the underside of the latter to theupper surface of the side plates. The rear side braces are secured tothe tie flanges, side plates and rear cross brace.

The derail may be readilyadapted for either level or canted railsystems. In the instant embodiment of the invention the derail is shownin connection with a canted system. The rail, illustrated by referencecharacter til, is supported upon tie plates 82 secured in conventionalmanner to the ties 54 and supporting the rail 80. The tie plates arenotched at their inner and adjacent corners, as indicated by referencecharacters 84 (see Fig. 1) to provide space for the horizontal tieflanges 58 and 52.

The derail guide box is adaptable exactly to fit any height or railwithout requiring adzing of the ties under the rail or guide box orwithout requiring shimming at the same locations. Furthermore, it isadaptable to systems in which the rails are supported on either level orcanted tie plates. The adaptability may be noted from a comparison ofthe embodiment of the invention to a system wherein the rail issupported upon level tie plates. The guide box is quite similar to theone previously described except that the horizontal tie flanges 5G and52 (like reference characters being used to indicate like parts) aredisposed vertically relative to the side plates and the lower ends ofthe side plates are not only parallel to the tie flanges but are alsoperpendicular to the side plates and base, as distinguished from beingtrimmed ofi" at an angle corresponding to the canting.

The derail guide box illustrated in Fig. 6 is of a full height, i. e.,it is dimensioned to fit the largest size rail (39A) of a series ofrails with which the guide box is intended to be used. The side plates30A, the front cross brace 46A, the middle side braces ltA and the rearside braces 53A have their maximum dimensions.

To adapt the guide box for a rail of lesser height '(rail 85B) it isnecessary only to trim off portions of the side plates (preferably) andthe front cross brace and to use smaller sized middle and rear sidebraces, as may be noted by comparing the elements 3M3, 56B, Hi3 and MBof Fig. '7 with the corresponding elements shown in Fig. 6, and tosecure the tie flanges 5!] and 52 and the braces at the proper positionsrelative to the side plates.

An adaptation to an even smaller size of rail (860) is illustrated inFig. 8 and here again the portions of the side plates and front crossbrace which are trimmed on are indicated by their respective referencenumbers followed by the suffix C.

The derail guide box is also adaptable to different spacing betweenties. All that is necessary to adapt it to different spacing is tochange the dimensions of the cross brace structure.

Another feature of the present invention is the provision of a derailguide box having unitary tie fianges and tie plates. A guide box of thischaracter is illustrated in Figs. 9 and 10. The guide box structureillustrated in Fig. 9 corresponds to that of the first describedembodiment, except for the construction of the unitary tie flanges andtie plates, which are indicated by ref- Gil erence character 98. It maybe noted, particu larly from Fig. 9, that the tie flanges are providedwith front portions 92 extending underneath and beyond the base of therail. The rail may be supported either level or canted upon this portionand in the illustrated embodiment it is shown supported in cantedposition. The canting of the rail is effected by a small pad 94 underneath the outer side of the rail base and having a vertical projection36 abutting against the rail. base to prevent the rail from moving awayfrom the derail. The extensions of the horizontal tie flanges areapertured, as indicated by reference character 98, through which spikesI extend in abutting relation with the flanges between to hold thederail in place.

It is readily apparent, therefore, that the derail guide box may readilybe adapted to fit any kind of track construction and may be installedwith the assurance that it will fit accurately. It is apparent also thatwhen the invention is utilized in conjunction with sliding derails, themovement of the derail block on and 01f the rail has the same relationto the rail as though both the rail and derail guide box were flat uponthe ties.

The derail guide box of the present invention may be readily fabricatedfrom a numer of parts which can be cut, forged and welded to form thebox. This is the construction employed in the embod'ments of theinvention described. However, some, or most, of the parts of the guidebox may be made as castings and assembled as by welding.

It i contemplated also, to avoid the work required to fabricate thevertical side plates and supporting and guiding structure mountedthereon of steel plate, that these structures may be made of steelcastings. Thus the side plates, together with the holding down shelvesit, the seats 42, and the pads as, may be made as single steel castings.

It is contemplated also that the derail guide boxes be made from asub-assembly unit which may be termed standard shell. This shell includes the vertical side plates and elements secured thereto and thefront and rear cross brace structure. This shell may be fabricated orcast as a unit and dimensioned to fit the highest rail of a series ofrails without change. The shell can be made to fit lower rails bytrimming off portions of the side plates and front brace, after whichthe horizontal tie flanges are secured to the side plates at properheights and desired anglee to adapt the guide box to desired trackconstruction.

Other modifications of the present invention will occur to those skilledin the art, and it should be understood that the specific details of thedescribed embodiments are not intended to be limitative of the inventionexcept in so far as set forth in the accompanying claims.
